I had this problem back when I first had my stroke and the hospital was still trying to get me back on my feet.
I had six appointments booked in at the hydro-pool in the central Bristol Royal Infirmary and first week appointment was fine as I found a BB space right outside the hydro-pool but the following week no spaces anywhere so had to ring the hospital to tell them I was outside but can’t park so was cancelling that and all other appointments.
What makes me mad is that the hospital asked the council for their multi-story car park to be knocked down and rebuilt with more spaces that was refused because they think everyone should be using the buses. I really hope our mayor and councillors rot in hell.
